    Abstract: A material may include grains of sizes such that at least 99 % of a measured area contains grains that exhibit grain areas less than 10 times an area of a mean grain size of the measured area. As examples, at least 99 % of the measured area may contain grains with grain areas less than 8, 6, or 3 times the area of the mean grain size. The grains may also have a mean grain size of less than 3 times a minimum statically recrystallized grain size, for example, a mean grain size less than about 50 microns, 10 microns, or 1 micron. The material may be comprised by a sputtering target and a thin film may be deposited on a substrate from such a sputtering target. A micro-are reduction method may include sputtering a film from a sputtering target comprising grains of sizes as described. A sputtering target forming method may include deforming a sputtering material. After the deforming, the sputtering material may be shaped into at least a portion of a sputtering target. The sputtering target may include grains of sizes as described. Also, the deforming may induce a strain level corresponding to epsilon of at least about 4. Further, the deforming may include equal channel angular extrusion.

    Abstract: The invention describes herein relates to new titanium-comprising materials which can be utilized for forming titanium alloy sputtering targets. The titanium alloy sputtering targets can be reactively sputtered in a nitrogen-comprising sputtering atmosphere to form an alloy TiN film, or alternatively in a nitrogen-comprising and oxygen-comprising sputtering atmosphere to form an alloy TiON thin film. The thin films formed in accordance with the present invention can have a non-columnar grain structure, low electrical resistivity, high chemical stability, and barrier layer properties comparable to those of TaN for thin film Cu barrier applications. Further, the titanium alloy sputtering target materials produced in accordance with the present invention are more cost-effective for semiconductor applications than are high-purity tantalum materials and have superior mechanical strength suitable for high-power sputtering applications.
